Pasadena, CA – The Dawn spacecraft has delivered a glimpse of Ceres, the largest body in the main asteroid belt, in a new image taken 740,000 miles (1.2 million kilometers) from the dwarf planet. This is Dawn’s best image yet of Ceres as the spacecraft makes its way toward this unexplored world.
“Now, finally, we have a spacecraft on the verge of unveiling this mysterious, alien world. Soon it will reveal myriad secrets Ceres has held since the dawn of the solar system,” said Marc Rayman, of NASA’s Jet Propulsion Laboratory in Pasadena, California, chief engineer and mission director of the Dawn mission.
Washington, D.C. – NASA and space agencies across the globe are opening up new possibilities for space exploration with missions to comets, asteroids, and other celestial bodies.
Following NASA, European Space Agency (ESA), and Indian Space Research Organisation (ISRO) spacecraft observations of the close flyby of Mars by comet Siding Spring in October, and the successful November landing of ESA’s Philae lander on comet 67P/Churyumov–Gerasimenko, the Japan Aerospace Exploration Agency (JAXA) successfully launched its Hayabusa2 mission on December 3rd to rendezvous with an asteroid, land a small probe plus three mini rovers on its surface, and then return samples to Earth.

Cape Canaveral, FL – NASA marked a major milestone Friday on its journey to Mars as the Orion spacecraft completed its first voyage to space, traveling farther than any spacecraft designed for astronauts has been in more than 40 years.
“Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space on our Journey to Mars,” said NASA Administrator Charles Bolden. “The teams did a tremendous job putting Orion through its paces in the real environment it will endure as we push the boundary of human exploration in the coming years.”

Washington, D.C. – On December 3rd, the Japan Aerospace Exploration Agency (JAXA) successfully launched its Hayabusa2 mission to rendezvous with an asteroid, land a small probe plus three mini rovers on its surface, and then return samples to Earth.
NASA and JAXA are cooperating on the science of the mission and NASA will receive a portion of the Hayabusa2 sample in exchange for providing Deep Space Network communications and navigation support for the mission.
Washington, D.C. – Orion’s managers for NASA, Lockheed Martin and the United Launch Alliance said they will push on with planning to launch Orion on its flight test Friday morning at 7:05am EST. The launch window will be 2 hours, 39 minutes, the same time span as Thursday. “Our plan is to fly tomorrow,” said Mark Geyer, Orion program manager.
Fill-and-drain valves on the Delta IV Heavy will be tested throughout the day so the launch team can prevent a mechanical problem like one that came up Thursday. “We’re very confident we’re going to be able to exonerate the equipment,” said Dan Collins, chief operating officer of United Launch Alliance.
NASA uses Keck Observatory telescopes to determine dust will likely not to block images of star’s Planets
Written by Whitney Clavin
Pasadena, CA – Planet hunters received some good news recently. A new study concluded that, on average, sun-like stars aren’t all that dusty. Less dust means better odds of snapping clear pictures of the stars’ planets in the future.
These results come from surveying nearly 50 stars from 2008 to 2011 using the Keck Interferometer, a former NASA key science project that combined the power of the twin W. M. Keck Observatory telescopes atop Mauna Kea, Hawaii.
Washington, D.C. – Managers from United Launch Alliance (ULA) and Lockheed Martin gave a “go” to proceed toward launch pending completion of open work during the Launch Readiness Review for Orion’s flight test. The weather is forecast to be 60 percent “go” for a scheduled liftoff at 7:05am EST on Thursday, December 4th.
NASA TV will air an Orion Flight Test Status and Overview briefing at 1:00pm today. On December 3rd, a prelaunch status briefing will be held at 11:00am. A NASA overview event with participation from social media followers will air at 1:00pm.

Pasadena, CA – A comprehensive, 21-year analysis of the fastest-melting region of Antarctica has found that the melt rate of glaciers there has tripled during the last decade.
The glaciers in the Amundsen Sea Embayment in West Antarctica are hemorrhaging ice faster than any other part of Antarctica and are the most significant Antarctic contributors to sea level rise. This study by scientists at the University of California, Irvine (UCI), and NASA is the first to evaluate and reconcile observations from four different measurement techniques to produce an authoritative estimate of the amount and the rate of loss over the last two decades.
Washington, D.C. – In the not-too-distant future, astronauts destined to be the first people to walk on Mars will leave Earth aboard an Orion spacecraft.
Carried aloft by the tremendous power of a Space Launch System rocket, our explorers will begin their Journey to Mars from NASA’s Kennedy Space Center in Florida, carrying the spirit of humanity with them to the Red Planet.
The first future human mission to Mars and those that follow will require the ingenuity and dedication of an entire generation. It’s a journey worth the risks.

Greenbelt, MD – Two donuts of seething radiation that surround Earth, called the Van Allen radiation belts, have been found to contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.
The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation.
